Personalized underwater message

Make your big moment even more magical at the Seattle Aquarium!

Whether you’re planning an anniversary, birthday, graduation, retirement, gender reveal or wedding proposal, celebrate here with our diver holding your special message.

How it works:
You and your loved ones will take center stage and become part of our Window on Washington Waters diver experience! Aquarium divers wearing specialized masks are able to talk with Aquarium interpreters and answer questions from outside of the exhibit. Bearing an underwater sign with your personalized message, our diver will help you brighten someone’s day or celebrate an important milestone.

As a fun bonus, the underwater sign will be a keepsake that you can take home as a souvenir!

To protect the health and safety of our guests, staff and volunteers, only a small gathering is allowed on-site to share these celebrations at this time. Alternative options, like making a video recording for family and friends, are also available.

Cost: $500
Subject to availability. Requires prepayment and must have two-week advance notice.
Includes Aquarium admission for up to four guests.
All signage must be family friendly and preapproved by the Aquarium.
